APPARATUS FOR LIFTING AND TRANSPORTING INVALIDS.

Specification of Letters Patent.

Patented Oct. 24,, 1905.

Application filed February 6, 1905- Serial No. 244,490.

To ctZZ whom it may concern:

Be it known that I, WILLIAM AMos, a citizen of the United States, residing at Providence, in the State of Rhode Island, have invented a new and useful Improvement in Apparatus for Lifting and Transporting Invalids, of which the following is a specification.

The nature of my invention consists, mainly, in the folding construction of the supportingframe and in the improved construction of the stretcher-frame and the lifting mechanism, as hereinafter set forth.

In the accompanying drawings, Figure 1 represents an end elevation of the apparatus when arranged over the bed, which is shown in section. Fig. 2 represents a top view of the apparatus. Fig. 3 represents a front elevation. Fig. 4 represents the front view of the apparatus when in its folded condition. Fig. 5 represents a top view of the same. Fig. 6 represents an enlarged axial section of one of the casters of the frame. Fig. 7 represents an enlarged section of one of the connecting-joints for the removable tie-rod. Fig. 8 represents an enlarged section of the joint of one of the inclined folding braces of the frame when in its closed condition. Fig. 9 represents the same when in its opened condition. Fig. 10 represents a section taken in the line 10 10 of Fig. 8.

In the drawings, A represents a movable frame comprising the base B, supported upon the casters C U and to which are connected the folding standards D D by means of the joints a 0,, the said standards being held in their upright working position by means of the removable tie-rod E. The standards D D are also connected to the base B by means of the inclined folding braces F F, which, are jointed to the base B at the points Z Z and to the standards D D at the points 0 c and have an intermediate folding joint (Z, the said joint being made of self-locking construction, the locking movement being effected by means of the sleeve G, which slides upon the ribs 0 a of the arms ff" of the brace F, the locked position of the joint of the said brace being shown in Fig. 8 and the opened position when ready for closing is shown in Fig. 9, in which the lockingsleeve Gr is caught and retained by the shoulder g of the spring H, which spring upon the complete closure of the joint will have been forced inwardly by its engagement with the projecting shoulder it of the lower arm f of the brace F, thus allowing the sleeve G to slide from the upper onto the lower arm of the said brace to lock the joint. The employment of the spring H for holding back the said sleeve until the arms ff of the brace F are brought in line with each other, and thus automatically effecting the locking engagement of the sleeve by the force of gravitation, constitutes a desirable improvement.

To the stretcher-sheet I are attached the straps 2' *6, provided with gromets which are adapted to receive the hooks or pins 7': 7 of the stretcher-frame J to which the stretchersheet is to be connected, and to the opposite ends of the stretcher-frame are connected the cords Z Z Z Z, which are connected to the stretcher-frame at opposite sides of its longitudinal axis, and pass thence over the pulleys Z1 is, which are held upon the forwardly-projecting arms K K of the standards D D, and thence to the winding-up pulleys m m of the winch L, located upon one of the said standards D, the said winch being operated by means of the crank M, the worm N, and worm-gear O. The cords Z Z after passing from the stretcher-frame over the pulleys 1; k pass downward over the guide-pulleys a a at the side of the standard D to the guide-pulleys 11/72, which are secured to the base B, thence along the said base and around the guide-pulleys 0 0, and thence up to the winding-up pulleys m m of the winch, whereby the said cords from opposite ends of the stretcher-frame will be wound up simultaneously, and by means of the winch L the invalid may be raised or lowered and sustained in any desired position while being transported from one place to another.

To the upper side of the stretcher-frame J are hinged the supplementary stretcherframes J J at the points 12 p, the ends of the stretcher-sheet I being secured to the said frames, thus serving to cause the elevation of the stretcher-sheet, so as to form suitable head or foot rests for the comfort of the invalid, the said rests beingsustained in their elevated position relatively to the stretcher-frame J by means of the short chains N" N, which at their upper ends are permanently connected to the arms K K of the standards D D and are hooked at will into the hooks (1 of the hinged frames J J or the hooks g of the stretcherframe J.

hen transporting the apparatus from one point to another at a considerable distance, itis desirable to hold the forward casters 0 of the frame in a fixed position, and to this end I provide the flange '1- of the casters with a perforation s, which is adapted to receive the pin 6, by means of which the caster will be maintained in its proper set position.

In operating the apparatus to raise the invalid from the bed the stretcher-sheet B is first drawn under the invalid, so that the invalid will lie centrally of the same, and then the lifting and transporting apparatus is to be brought forward with the stretcher-frame raised to its highest elevation, so as to pass over the invalid resting on the stretcher-sheet. Then the frame J is to be lowered down to the bed and the stretcher-sheet secured thereto by means of the gromet-straps e' 2', which are to be hooked over the hooks or pins L is of the stretcher-frame J and of the hinged frames J J. Then upon turning the winch L in the proper direction the invalid may be raised from the bed and transported either to another bed or to a bath-tub, as desired, or be comfortably supported while the bed is being made up for return thereto, the invalid being so raised and transported as to cause no discomfort or pain, and in carrying the invalid back to the bed the operation will be reversed. WVhen it is desired to cause the stretchersheet to be raised at either the head or foot, so as to support the invalid in an easy position, the chain N is to be hooked into the book 9 of the hinged frame J and then the stretcherframe J lowered, so as to bring the hinged frame J to the desired inclination, and when it is desired to cause the inclination of the stretcher-frame J the chain N may be hooked into the hook q of the said stretcher-frame.

In folding the apparatus when not in use the tie-rod E is to be removed from the jointears a a of the standards D D and the said standards folded down upon the base B, as

shown in Figs. a and 5, and in this case the apparatus may be packed away in a comparatively small space, which is a very desirable feature in an apparatus of this character.

I claim as my invention 1. In an apparatus for lifting and transporting invalids, the combination of a movable base supported upon rollers, and adapted to extend under the bed with the standards jointed to the base for inward-folding movement, and having the projecting arms adapted to extend over the bed, the folding braces for the said standards, and the removable tie-rod, substantially as described.
